title	User Control Actions in Buildings: A Case Study of Shading
source	Vienna University of Technology; Building Science & Technology
summary	This thesis describes the results of a research to find out how users interact with shading and lighting devices in an office building in Vienna, Austria. The aim of the research is to explore the parameters that lead occupants to change shade positions. For this purpose, changes in shading on the southwest and north façades of the building were observed by capturing images of the whole façade. Weather conditions were registered by the weather station mounted on the top of the building. Inside the building, 15 rooms on the southwest façade and 14 rooms on the north façade were selected. Users’ operation of lighting was captured in each room. Data over a period of twelve months was collected and analyzed. The relationship between users’ behavior and environmental parameters was studied. The potential for energy saving through the use of occupancy sensors was explored.

summary	The design of a city has a great influence on its society. Therefore, current/future cities must be understandable by everyone, regardless of their ability to use technology. Various tools have been used to show urban spaces. The authors focused on SCMODs (physical scale models), and VR (Virtual Reality). These are three-dimensional and intuitive expression methods. In this study, a city presentation method offering a united operating environment linking viewpoint information between a SCMOD and VR is developed and evaluated. Photogrammetry acquires aspect information with a laser pointer, an AR marker and a web camera. To evaluate this method, 36 testees answered a questionnaire after experiencing the method. The testees evaluated the method positively.

title	Music Composition with Interactive Evolutionary Computation
source	International Conference on Generative Art
summary	Interactive Evolutionary Computation (IEC), i.e., Evolutionary Computation whose fitness function is provided by a user his/herself, has been applied to esthetic areas, such as art, design and music. We cannot necessarily define fitness functions explicitly in these areas. With IEC, however, we can embed the user's implicit preference into the optimization system. This paper describes a new approach to music composition, more precisely the composition of rhythms, by means of IEC. The main feature of our method is to combine Genetic Algorithms (GA) and Genetic Programming (GP). In our system, GA individuals represent short pieces of rhythmic patterns, while GP individuals express how these patterns are arranged in terms of their functions. Both populations are evolved interactively through the user's evaluation. The integration of interactive GA and GP makes it possible to search for musical structures effectively in the vast search space. In this paper, we show how successfully our proposed method can generate attractive musical rhythms. The effectiveness of our system is demonstrated by the evolved rhythm phrases, which are available from our web site as sound files.

title	Virtual situation rooms: connecting people across enterprises for supply-chain agility
source	Computer-Aided Design, Vol. 32 (2) (2000) pp. 109-117
summary	Agility and time-based manufacturing are critical success factors for today's manufacturing enterprise. To be competitive, enterprises must integrate their supply chains moreeffectively and forge close memberships with customers and suppliers more quickly. Consequently, technologies must be developed that enable enterprises to respond toconsumer demand more quickly, integrate with suppliers more effectively, adapt to market variations more efficiently and evolve product designs with manufacturing practicesmore seamlessly. The mission of the Extended-Enterprise Coalition for Integrated Collaborative Manufacturing Systems coalition is to research, develop, and demonstratetechnologies to enable the integration of manufacturing applications in a multi-company supply chain planning and execution environment. We believe real-time andasynchronous collaboration technology will play a critical role in allowing manufacturers to increase their supply chain agility. We are realizing our efforts through our VirtualSituation Room (VSR) technology. The primary goal of the VSR technology is to enhance current ad-hoc, limited methods and mechanisms for spontaneous, real-timecommunication using feature-rich, industry standards-based building blocks and network protocols. VSR technology is being designed to find and engage quickly all relevantmembers of a problem solving team supported by highly interactive, conversational access to information and control and enabled by business processes, security policies andtechnologies, intelligence, and integration tools.

title	Using an Online Participation Tool to Collect Relevant Data for Urban Design - The construction of two participation exercices
doi	https://doi.org/10.52842/conf.caadria.2019.2.747
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 747-756
summary	This paper discusses the design of an online digital participation campaign, developed as an academic research project in Singapore. In order to develop appropriate exercises which fitted the tool and the context, we addressed several questions: how can online participation tools maintain a negotiation and education power? What data generated by citizens, in the form of a design proposals, is useful for urban design? We created two different exercises, at different scales: one exercise asking people to design proposals with functional blocks and one where citizens could decide the equipment and furniture in a public space. For each exercise we discuss the scale, the elements, the educating and mediating impact, but also the way we intended to use the gathered local knowledge in urban design. The exercise did not receive the expected contributions, gathering little attention from internet users. More results were obtained using an offline experimental setup. In conclusion, we reconsider the weakest points of the design in a critical analysis and provide direction for future online participation tools.

title	Cultural-Smart City: Establishing New Data-informed Practices to Plan Culture in Cities
doi	https://doi.org/10.52842/conf.caadria.2020.2.081
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 81-90
summary	The idea of the Creative City has encouraged planners to develop cultural policies to support creative economies, city branding, urban identity and urban quality. On the other side, the concept of Smart City introduced the possibility to create, collect and analyse data to inform decisions on cities. The two city agendas overlap in different ways, creating a Smart cultural city nexus, that propose similar goals and mixed methodologies, like the possibility to inform planning processes with big data-based technologies. In line with this direction, we introduced conceptual and methodological tools: the first tool is the definition of Hybrid Art Spaces, the second tool is the Singapore Art Maps (SAM), which uses social media data to locate art venues in cities (Tomarchio et al. 2016); the third tool is the Social Media Art Model, which establishes a relationship between social media production and art venues features. While these tools have already shown interesting analytics outcomes (Tomarchio et al. 2016), it is important to validate their utility among practitioners and to set protocols of practices. This paper presents results from semi-structured interviews and a focus group, as a first step towards assessing the usefulness of our three tools for cultural planning practice.

title	Mapping Planned and Emerging Art Places in Singapore through Social Media Feeds
doi	https://doi.org/10.52842/conf.ecaade.2016.2.437
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 437-446
summary	This paper presents a methodology to collect and visualize social media data about art, in order to map art locations in cities using geo-localized data, and comparing planning decisions with the actual use of spaces. As various social networks have penetrated into the daily life of people, these become one important and effective data source to understand how people perform 'arts' around the city [Shah, 2015]. The case study for this methodology is Singapore, a vibrant city where art and culture are being promoted in the light of an emerging creative economy. The Singapore government promotes art and creates 'art clusters', such as art districts, galleries, fairs and museums in the city. Additionally, artists, creative entrepreneurs, consumers, and critics seek and explore alternative spaces. Understanding where art and creativity are discussed, broadcasted and consumed in Singapore is a key point to have better insights into art space planning, and study its effects on the city.The paper will try to answer the following research question:Is it possible to discover, through social network data, spaces where art is produced, discussed, and broadcasted to an audience in Singapore? How?

title	Drafted Virtual Reality - A New Paradigm to Design with Computers
doi	https://doi.org/10.52842/conf.caadria.2004.829
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 829-844
summary	This paper proposes a new technique for designing spaces, called Drafted Virtual Reality (DVR), to be used in interior, architectural or industrial design. It proposes the construction of virtual panoramic environments through the QuickTime VR (QTVR) Panorama platform (Apple), starting from sketches made by hand using traditional pen-on-paper techniques. To construct these drawings, the designer uses the computer to build a graphic panoramic template. Using this technique, the designer takes advantage of both approaches, the capacities and possibilities of the computer using VR (3D environments, interaction and real-time), and those of free-hand sketches (abstraction, inaccuracy and ambiguity). These last elements are essential for the first steps of the design process in contrast to the conventional techniques of 3D modeling interacting with mouse and menus. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems very different than how designers actually work. The DVR doesn’t try to simulate analog tools by computers (digital pens), but takes advantage of hand drawn sketches created using analog techniques that are already known by designers and improved by VR visualization. A review of the implication of this technique on the design process. Not only is the technique fast and easy to learn, the results show that the designer can express their individuality and the idiosyncrasies of their personal sketches; important elements hard to achieve with conventional 3D modeling techniques. Finally, this technique can be perceived as a new paradigm in the way we work with computers in design. The limitations of interfaces and usage of current technology are seen when the designer outputs information from the system to process using other analog techniques. The proposed solution marries the existing competencies and techniques of the designer with the advantages of the computer processing. The quality of the virtual experience of this technique is consistent with current designer’s intentions within the traditional design process.

title	Generative Methods in Kindergarten Designing
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 61–68
summary	There are many obese children worldwide, for which the lack of physical activity is the main reason. During early childhood, children spend most of the day in kindergartens. Many studies show that the kindergarten environment can form a suitable context for implementing interventions to engage in physical activity through its functional organization. This paper offers an algorithm for floor plan generation to ensure all necessary daily activities in the kindergarten with the increase of movement as a physical activity of moderate intensity with a tendency towards values recommended by the World Health Organization. Magnetizing Floor Plan Generator is chosen as a tool for generating floor plans with input data: space for each activity represented as a room with the area necessary for carrying out activities and the connections between them according to kindergarten guidelines. In the Galapagos component in Grasshopper, the fitness function will then be set to increase the corridor area, and finally, through iterations, a solution with the largest corridor area will be obtained, i.e., potentially the longest movement path.

summary	This research explores an application of multi-agent systems to the generation of single- layer branched shell structures for architectural application. The study is prompted by the structure and pattern-making capacity of climbing plants’ growth behaviours, in which growth history (affected by internal local processes and environmental conditions), generates a multi-performant outcome. The digital system merges parts of the Space Colonization Algorithm (SCA) with agent-based logic, leveraging iterative local interactions to coherently embed environmental conditions and static requirements in the production of a coherent structural network on a boundary surface, which is translated in a beams-and-nodes glued laminated timber structure. The paper exposes the method and its applications to the case study of a pavilion, discussing geometric constructability’s challenges and limits.

source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This article presents the design process for generating a shell-like structure from an activated bent auxetic surface through an inductive process based on applying deep learning algorithms to predict a numeric value of geometrical features. The process developed under the Material Intelligence Workflow applied to the development of (1) a computational simulation of the mechanical and physical behaviour of an activated auxetic surface, (2) the generation of a geometrical dataset composed of six geometric features with 3,000 values each, (3) the construction and training of a regression Deep Neuronal Network (DNN) model, (4) the prediction of the geometric feature of the auxetic surface's pattern distance, and (5) the reconstruction of a new shell based on the predicted value. This process consistently reduces the computational power and simulation time to produce digital prototypes by integrating AI-based algorithms into material computation design processes.

title	Design and Fabrication of 3D Reciprocal Frame Structure

summary	Reciprocal frame structure is a special type of spatial struc- ture, which consist of elongated elements. The elements support each other along their span, compose a stable geometrical configuration without any clear structural hierarchy. Based on the morphology, the reciprocal frame could be categorized to 1D, 2D, and 3D. Compared to 1D and 2D, 3D reciprocal frame presents some novel features. It shows a growing pattern with some simple rules. Even with the same rule, 3D reciprocal frame could grow up to different form. It’s a typi- cal process of bottom-up which implies a considerable wealth of pos- sibilities. Study on the 3D reciprocal frame gives the potential for achieving novel and complex forms. With the restriction of the cate- gory of 3D reciprocal frame, the paper summarized the characteristics of the frame as growth, regularity, and spatiality. And the structure should be repeated, simulated, and constructed. The paper also ex- tracted three basic factors - growth rule, initial form, and bar size. Through the simulation experiments with different factors, the rela- tionships between the frame shape and the factors were established. At the end, a full-scale model validates the feasibility of the growth result of 3D reciprocal frame.

title	Comparison of Partitioning Methods for Estimating the Layout of Green Spaces
doi	https://doi.org/10.52842/conf.caadria.2014.873

summary	The urban green space positively affects the quality of the environment and urban life. To estimate the layout of urban green spaces, especially to describe the real difference of regional properties, the influenced zone of each green space should be identified firstly. The influenced zone can be used to quantitatively analyse the difference of regional environmental quality. The identification of the influenced zones of green spaces actually is a problem of space partitioning. The study compared three methods mostly used in space partitioning. The regular grid is a most common partitioning method. It is easy to use, but cannot link the grid with green space separately. Voronoi algorithm is a constructive method which partitions the urban space based on each green. Another approach is the application of gravity models, which assumed analogies between human behaviour and Newtonian gravity laws. The gravity model could calculate the probabilities of residents to choose the green space and partition the urban space. In the comparison of these three methods, we conclude that the gravity model can take more characteristics of the green space as the calculating parameters. The gravity model is a better method to estimate the layout of urban green spaces.

summary	New construction within existing buildings requires documentation of the existing buildings, in a form that one is familiar with from new construction or architectural design. Laser scanning is a powerful tool to survey the built reality. It provides a replica of the existing building in the form of a point cloud. The difficulty is to analyse the resulting amounts of data that has been generated and being able to interpret it as a Building Information Model (BIM). This article proposes a new generic approach for pattern recognition of architectural objects. The procedure is introduced through the use of two examples - polygon fitting, which is important for the generation of new building element classes and wall detection. The second part describes how individual components can be automatically connected to consistent networks. BIM systems walls should be aligned, within predefined limits of accuracy, either perpendicular to or in line with each other.

summary	Empirical cycling data from across the world illustrates the many barriers that car-dependent cities face when implementing cycling programs and infrastructure. Most studies focus on physical criteria, while perception criteria are less addressed. The correlations between the two are still largely unknown. This paper introduces a methodology that utilises computer vision analysis techniques to evaluate 15,383 Google Street View Images (SVI) of Brisbane City against both physical and perception cycling criteria. The study seeks to better understand correlations between the quality of a street environment and an urban area's 'bicycle-friendliness'. PSPNet Image Segmentation is utilised against SVIs to determine the percentage of an image corresponding with objects and the environment related to specific cycling factors. For physical criteria, these images are then further analysed by Masked RCNN processes. For perception criteria, subjective ranking of the images is undertaken using Machine Learning (ML) techniques to score images based on survey data. The methodology effectively allows for current findings in cycling research to be further utilised in combination via computer visioning (CV) and ML applications to measure different physical elements and urban design qualities that correspond with bicycle-friendliness. Such findings can assist targeted design strategies for cities to encourage the use of safer and more sustainable modes of transport.

summary	Sports disciplines have evolved in recent decades to improve the performance of athletes, as a result of interdisciplinary convergence. Computational Fluid Dynamics (CFD) and wind tunnel have gained relevance in sports design to predict the aerodynamic behavior. On the other hand, Bio-informed disciplines study nature to solve human problems, in order to generate innovation with or without sustainable results. This text presents a first proposal of a methodology oriented to the evaluation, analysis, and selection of bioinspired digital textures, in order to improve the aerodynamic performance in sports product design, through the integration of CFD and wind tunnel testing.
